What You Need to Know About Vitamin D

By Health Day – Re-Blogged From Newsmax

You’d think vitamin deficiencies would be rare in the United States, but many people are running low on vitamin D, and it’s a serious health threat.

Being short on vitamin D not only affects bone density, it’s also been linked to conditions such as heart disease, mental decline, some types of cancer, autoimmune diseases, infectious diseases and type 2 diabetes.

The problem is twofold: Not knowing how much vitamin D you really need, and how to get it. While 600 to 800 International Units (IUs) is the recommended daily amount, it can take more than that to bring you up to a healthy level and maintain it once you have a deficit.

Solar Cycle Update for November 2018

By David Archibald – Re-Blogged From WUWT

In reading the solar data, what we are after in the near term is the likely month of minimum for the Solar Cycle 24/25 minimum and likely amplitude of Solar Cycle 25. Of course that quest for truth gets easier as we approach the minimum, at least apparently. Solar Cycle 24 looks like being unusual in being short while being weak and Solar Cycle 25 looks like being a repeat of Solar Cycle 24 in terms of amplitude.

The concept of the Super Grand Solar Deepest Minimum is fashionable again for the moment. There is no sign of that in the data. That said, activity in Solar Cycle 24 was back-loaded and if the solar activity to atmospheric temperature connection is real, the planet’s temperature will be running warmer for a few more years as a consequence of that.

The Chill of Solar Minimum

Sept. 27, 2018: The sun is entering one of the deepest Solar Minima of the Space Age. Sunspots have been absent for most of 2018, and the sun’s ultraviolet output has sharply dropped. New research shows that Earth’s upper atmosphere is responding.

“We see a cooling trend,” says Martin Mlynczak of NASA’s Langley Research Center. “High above Earth’s surface, near the edge of space, our atmosphere is losing heat energy. If current trends continue, it could soon set a Space Age record for cold.”

Solar Symmetry and Balance

By Willis Eschenbach – Re-Blogged From http://www.WattsUpWithThat.com

The CERES satellite dataset is a never-ending source of amazement and interest. I got to thinking about how much energy is actually stoking the immense climate engine. Of course, virtually all the energy comes from the sun. (There is a bit of geothermal, but it’s much less than a watt per square metre on average so we can ignore it for this type of analysis).

So let’s start from the start, at the top of the atmosphere. Here’s the downwelling top of atmosphere (TOA) solar energy for the northern and the southern hemisphere:

The Source Of The Heat

By Willis Eschenbach – Re-Blogged From http://www.WattsUpWithThat.com

Over at Dr. Judith Curry’s always excellent blog, she has a post headlined by a question, viz:

What are the main sources of heat that account for the incremental rise in temperature on Earth?

Let me start by saying that this is a horribly phrased question. Consider a parallel question:

What are the main sources of heat that account for the incremental rise in my body surface temperature when I put on a jacket?

Forecast for Solar Cycle 25

By James A. Marusek – Re-Blogged From http://www.WattsUpWithThat.com

I. Introduction

The sun is the natural source of heat and light for our planet. Without our sun, the earth would be a cold dead planet adrift in space. But the sun is not constant. It changes and these subtle changes affect the Earth’s climate and weather.

At the end of solar cycle 23, sunspot activity declined to a level not seen since the year 1913. [Comparing Yearly Mean Total Sunspot Numbers1]
